Hi Zach007,
Depends on the license you buy. If you buy both InfoPathDev Forms Viewer and InfoPathDev Database Accelerator, you can input fields into a database, but not all fields. Just radio buttons, dropdowns, text fields, dates, and other simple fields. The Forms Viewer doesn't support entry for all controls (for example, digital signatures and file attachments are not supported).
